Application filed my 11, 1925. 'Serial No. 29,544.
' To all whom it may concern:
Be it known that I, ARTHUR C. TUNIsoN, a citizen of the United States,.residing at Los Angeles, in the county of Los Angeles tain new and useful Improvementsin Longolear, and exact descriptionof the invention, such as will enable others skilled in the art to which appertains to make and use the 2 it is transferred from the lift mechanism at the top of the well to the pump at the bot-v tom of a deep well,agreat part of the length of the stroke is lost.
25 Itlis an object of the'invention to increase the stretch will not be detrimental tothe pumpingloperation and to the actual out-put 'with the movable rack bars and with the of the .well. A
Another object of the invention-isto -pr i 30 vide a compact mechanism suitable for construction at the top'of a well, and in which I the additional stroke length may be accomrespect to theomovable rack bars, and such stationary rack bars are suitably braced by plished without the application of further 3 power orfurther operating expense.
Figure 1 is a side viewvwith parts shown in section of an improved lift mechanism constructed accord ng to the present invention, 4

Referring more particularly to the'drawtugs 3designates the well casing and-4 the rods extending fromrlthe lift mechanism n ws tothepump atthe bgtton of the well,
the stroke or the travel of the rods, so "that With the foregoing andfother objects in parts through Figure 3 is a horizontal section taken on I At 5 is indicated a platformon which are laid the beams'fi and 7 at opposite sides of the well shaft,,these beams receiving the tracks 8 and 9 upon which the flanged roll 5 and State of California, have invented cerp p p to roll. Stroke Lifts for Pumping ells; and I do A herebydeclare the following to be a full,
ers 10 and 11 of the carriage 12 are adapted l The carriage is constructed in any suitable manner as for instance in part by the,
"direction with their flanges turned away from each other. The flanges providev for receiving the bearings 16 and 17 for the flanged wheels 10 and 11; I
The beams 12, 13 and 14, receive the pairs of rollers 18 and 19, these rollers being disposed upon opposite sides of the guides 20 and 21 for the movable rack bars 22 and 23 which may extend in one piece with the guides 20 and 21; the guides and the movable rack bars being arranged to movesubstantially vertically. The pumprod extends up through the casing 3, and is secured to a cross head24 connecting the upper ends o-f'the two movable rack bars 22 and 23. Traveling pinions 25' mesh both stationary rack bars 26 and 27 disposed opposite the movable rack bars. The stationary rack bars are erected on the carriage or truck in parallel and spaced relation with ing rods or pitman rods 31 and 32, the lower ends of which are adapted to be driven from the gearwheels 33 and 34 to which said con- 3 v necting rods are secured by the pins. I In Figure 1,four pins 35, 36, 37 and 38 are shown all as located at progressively greater distances from the center of rotation of the gear wheels whereby the, stroke of the connecting rods may be varied at will by selecting an appropriate pin. Thegear wheels 33 and 34 are mounted on the shaft'39 and said gear wheels are disposedinmesh with pinions 40driven by the belt 41 from an appropriate source of power. through the pulley 42 associatedwith said gear wheels 40. I g r 3 the s ationary rack bars 26 and 27 are shown as attached to the outer side of the near flanges and 61 of the I beams 62f and 65; while the opposed flanges 62 and 63 provide guide ways for the rollers 66 and 67 journaled upon shafts 6S and 69 whiohare carried 'in' the rear arms 70 and 71. These arms are arranged upon the sleeve 72 which fits loosely over the shaft 30 between the pinions and between'the thrust rollers 73 and 7% which are mounted on the shaft 30 and travel up and down opposite the guide rolls 66 and 67 upon the flanges 62 and 6 of h I b ams- :The u d beams 20 @121 to which the: movable rack bars 2 n 23 ar ttadmd are a so P efe a ly,

' The guide rollers a l are in alineinent with t e We ra k d h i nlhi l'v i le th guide llerf '6 an '6 e in fel nem t-vith the thrust r rs 5- As show in F g e 1 the m h de TQ QI .66 and 67 are preferably mounted in pairs one above the other in the arms 70 and 71, while the forward guide'rollers 4A are single rollers. The double rollers in the rear will prevent any oc ing iiie en iit f he" sleev in a v t ca pl s such a may ca se dis inement or binding of the parts, There willalw y e f edom f m veme t betw n the pinion teeth and the teetl 'of the rack bars.
In the use ofthedevice, the belt arrangement ll will drive the pinions 40 andin. t i m n er th gear Whe l 3 andfid will be e C y ng mend ther w th con necting rods 31 and 32 an d causing the shaft '30 and the traveling pinions 25 to'be alternately lifted and lowered.
